目的 汽车人机交互系统具有复杂、动态的特点，日益普及的车载电子信息系统人机交互界面存在实时信息密集、多维的现象。通过对人的无意识认知模式特征进行研究，并以此对汽车驾驶位车载电子仪表盘界面布局进行优化设计，引导用户在驾驶汽车过程中将认知资源集中于驾驶主任务。方法 以人的无意识认知加工过程与用户行为模式之间的联系为基础，总结车载电子仪表盘界面布局设计原则，提出核心视觉信息布局设计的优化方案，并通过用户调研数据及可靠性检验对设计方案可用性进行验证。结论 基于无意识认知交互界面布局设计原则，设计出的车载电子仪表盘界面布局符合用户的认知习惯，满足用户的使用需求。

Automotive human-computer interaction system is complex and dynamic. With the increasing popularity of the in-vehicle electronic information system, massive intensive multi-dimension real-time information has been implanted in the system. To ensure the driver focus the unconscious cognition on the primary driving task in the complex and dynamic interaction system, human unconscious cognition can be used to guide the design of in-vehicle information system user interface and optimize the interface layout of the vehicle electronic instrument panel in the car driving seat. The design guidelines are based on the combination of human unconscious cognition and behavior pattern. The design guidelines summarize the principles of interface layout design of vehicle electronic instrument cluster, put forward the optimization scheme of core visual information layout design, and verify the usability of the design scheme through user survey data and reliability test.By following the guidelines of user’s unconscious cognition pattern, we can improve the design of in-vehicle electronic cluster which conforms to the user’s unconscious cognition and needs.
